K&N 57 vs Ingen PF series

I'm looking to put a ram or cold air intake on the new truck, and I've narrowed it down between the K&N 57 series and the Ingen PF series. from what I've been reading the K&N is more of a Ram air design whereas the Ingen is an actual cold air design. The Ingen is a little more expensive at about $300 but it seems legit. I'm curious if anyone has any experience on either setup and what you think of them.

I don't have that kind of system on my truck, but I do run a K&N filter. I do it for cost reasons because the filter is washable and re-useable. I like their filters.

I belong to the Puget Sound BMW CCA and we had a guy with an M5 test his car at our annual Dyno Day, with and without a K&N cone/ram air type intake system on a dynomometer. No change in horsepower or torque was seen (I was right next to the car when it ran on the dyno). We all were surprised, as we had bought into the hype by K&N about "less restriction=more power".

So, don't get your hopes up too high about a "performance increase" with these aftermarket filter/ram air intake accessories. If you like how it makes your truck engine compartment look, then get that one. Your OEM system is engineered to work well with the OEM configured motor. If you diddled with the CPU or you changed the camshaft, then maybe one of these aftermarket things might help a little, but based on my experts here who did a bunch of modifications to my motor, that stuff provides either little or no performance increase whatsoever.

I'm wondering Same thing but I had a K&N CAI on my 95 Camaro w/ 400Hp so i'm definitely biased to look at K&N am actually looking at one now I have a NBS 07 4.8L.. I recommend buying your CAI off amazon save ya like 50-100 bucks...
